Comment 69 for bug 1967632

It would be a big limitation if the solution to this focuses entirely on pcsc-lite:

a) /var/run/pcscd/pcscd.comm is internal and varies between distributions and pcsc-lite versions. I.e. any pcsc-lite library embedded in the snap package is not guaranteed to be able to talk to the system pcscd

b) Remote desktop solutions such as ThinLinc or FreeRDP tend to override the pcsc library so that smart card access can be tunneled.

I would suggest having a more generic tunnel between the snap and the session the snap is running in. Either on the PC/SC layer, or on the PKCS#11 layer. The session side of that tunnel would then hopefully respect the session environment fully.
